I'd be glad to spend some time perusing and attempting to understand an 
example (the simple the better, of course) for which

      ToExpression["soks"] /. ruleOne  

and

      soks /. ruleOne

typed into separate Input cells under identical starting conditions, 
where 'soks' is a sequence of key strokes, yield differing results when 
evaluated.
